That’s a fair point, although I would say socialism is becoming less fringe, and it seems like the various types of libsoc are the main forms of socialism because people have seen the failures of state based solutions, even amongst demsocs/socdems.

That said, I kind of agree and the word “fringe” didn’t sit quite right. On reflection a better word would be “covert”, since ideologies that explicitly want to dominate people tend to hide what they are, since they know it’s not acceptable to state their aims up front. That’s really the idea I was getting at.
